OPTIMIZATION AND PROCESS FLOW OF LABORATORY BASED LIQUID HANDLING ROBOT

Abstract

A machine is a mechanical device or structure which uses power to start the device. The machine converts the electrical energy into the mechanical energy. The mechanical movements will control the actions to be performed. Machines can be driven by so many means, like humans, animals, natural forces like wind, water, thermal, chemical and also electrical. We use sensors and actuators to run the machine. The actuator inputs are taken into account to achieve a particular application of output movements and forces. We also use computer programming and embedded programming for the movements, to monitor the performances and for the movement planning. A Liquid Handling robot is one such machine which takes the electrical energy and convert that into mechanical. It is type of machine which is used for the automation of chemical liquids and biomedical laboratory solutions. It dispenses a particular amount of liquid/reagent in a designated test tube which contains the substrate. The reaction happens after that. A simple machine of liquid handling robot just dispenses an allotted amount into the test tube. But more complicated machine not only just dispense the liquid, it can also change the position of the test tube, can take the test tube and keep in a spectrometer for the analysis and can also include many other laboratory devices. The machine has more than 94% accuracy in the testing for which it is well suited in laboratories.
